Hi Johannes,
Thanks, it works now, but the input will be without quotes, i.e., False not
`False`.

Re: [Discuss-gnuradio] gr-ieee-80211: UDP Warning and another error
Hi Sumit,
this is not an installation error. Your configuration is wrong. The
argument `enb` must be of type bool but it is a string in your case.
I assume you use GRC to generate this flowgraph.
Open your USRP source block. Go to the `FE Corrections` tab and put in
`False` in both fields. No `, ' or ". This will generate a line that says:
`self.uhd_usrp_source_0.set_auto_dc_offset(False, 0)`
instead of
`self.uhd_usrp_source_0.set_auto_dc_offset("False", 0)`.
This should fix your issue.
Cheers
Johannes

Its overwhelming :D, I have a demo on Monday and I was 100% assured
gr-ieee-80211 will work as usual.
Before I saw your mail, I already checked out GR to 3.7.12, UHD to 003 009
006 and compiling now.
Yes I used pybombs for installation.
I have a USB with gnuradio installed into it. It works good and it has GR
3.7.11, uhd 003 009 006 and gr-ieee-80211 version I dint check.

Re: [Discuss-gnuradio] gr-ieee-80211: UDP Warning and another error
Hmmm ... well the current UHD API for "set_auto_dc_offset" is "(bool, size_t)".
Looks like the generated Python from gr-ieee-80211 is "set_auto_dc_offset("",
0)", which isn't compatible with the current UHD API for this method.
Hmmm ... here's my best bet: gr-ieee802-11 uses the GR-provided GRC blocks
(whether XML or YML). Guessing you're using some reasonably recently (e.g.,
2019) GR 3.8-tech-preview commit. If that's the case, then here's what seems to
be the issue ... In this commit <
https://github.com/gnuradio/gnuradio/commit/4804d1fdb6950d2b2ec5707cd8a362f01ed2cf90

You said you used PyBOMBS to install everything ... yes? The UHD is the current
GIT master, so bleeding edge LOL.
Any way you can figure out which commit of GNU Radio and gr-ieee-80211 were
used? The latter was recently updated such that the GIT master corresponds to
GR 3.8, while "main-3.7" is for the current GR "maint-3.7" branch ... - MLD

Re: [Discuss-gnuradio] gr-ieee-80211: UDP Warning and another error
I'm no expert on what to change here, but I'd guess there's another setting
that's the correct one for your specific OS & version, and that
"net.core.rmem_max" is the correct one for some other OS and/or version. Maybe
do a quick internet search for how to change the UDP buffer size on your OS and
version? Maybe someone else in GR-land has seen this issue & knows what to do?

Hi Sumit - Just out of curiosity, have you tried the command the warning asks
you to execute?
{{{
sudo sysctl -w net.core.wmem_max=250

If not then please try it & see if that helps. - MLD

[Discuss-gnuradio] gr-ieee-80211: UDP Warning and another error
OS: Ubuntu 18.04
Laptop: Dell Latitude 5490
GNU Radio : 3.7.13.5
UHD : UHD_3.15.0.git-1-gf83faf28
SDR: Ettus N200
I did a fresh install today using pybombs.
Then tried running wifi_rx.grc from gr-ieee-80211 package and flooded with
errors. Never seen them before. Bold marked part is coming with all the
programs where I am connected to USRP such as uhd_fft while the rest
happens with wifi_rx.grc (this is what I have observed so far).
However, all the programs are working flawlessly with older version.
Any tips to solve it.
Regards
Sumit
